Distances is a table of distance monitors (measurements that update if there are changes). The tool also allows adding and deleting distance monitors, adjusting their appearance, and saving the information to a file. Distances is tabbed together with the Angles/Torsions and Axes/Planes/Centroids tools into a Structure Measurements window.
Distance monitors are pseudobonds. They can also be added with the distance command, selection context menus (when two atoms are selected), and the distance mouse mode . The tape measure mouse mode adds a different type of distance measurement with markers and links (details...).

Distances can be opened from the Structure Analysis section of the Tools menu and manipulated like other panels (more...).
